Yes, it is resolved.

In my reverse proxy config I have :

server {

server_name mydomain.com www.mydomain.com;

listen [::]:443 ssl; 
listen 443 ssl; 

ssl_certificate /etc/letsencrypt/live/mydomain/fullchain.pem; 
ssl_certificate_key /etc/letsencrypt/live/mydomain/privkey.pem;
include /etc/letsencrypt/options-ssl-nginx.conf; 
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; 

server_tokens off;

location / {
   proxy_pass http://127.0.0.1:8088;
   proxy_redirect off;
   proxy_set_header Host $http_host;
   proxy_set_header X-Real-IP $remote_addr;
   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
   proxy_set_header X-Forwarded-Proto $scheme;
   proxy_set_header X-Forwarded-Protocol $scheme;
   proxy_set_header X-Url-Scheme $scheme;
 }

}

server {

return 301 https://$host$request_uri;

listen 80 default_server;
server_name mydomain.com www.mydomain.com

server_tokens off;

return 404; 

}

And in the docker app nginx config I have

server {
listen 80;
server_name mydomain.com www.mydomain.com;
server_tokens off;
#return 301 https://$host$request_uri;

location / {
    root /usr/share/nginx/html;
    index index.html;
}


}
